i5 6600k clocked to 4.5ghz
It is my processor that is the most stressed in AC. definitely in ACC.
Noticeable improvement In frame rate for me came from Ram, 2133 to 3666Mhz
Reducing the number of App's on screen made a "very big" difference to FPS.
Before my 3440 x 1440 single screen I had triple 1080 monitors, could quite often get 144HZ with the
980Ti, possible with carful management of AC parameters.
unfortunately computer did a funny and I lost all my AC Benchmarks, all that remains of some use
is the data below.
You can probably make a good judgement between the 1080 and 2070 super, but you will need
to factor in your CPU.
